The National Capital Region Police Office earlier ordered an investigation of a memorandum addressed to Valenzuela police stations about an alleged plot to bomb several areas in Metro Manila that was leaked on social media.

"Following this, I have ordered the Northern Police District Director Bong Fajardo to investigate the document handling procedure at the Valenzuela Police Station," NCRPO Director Oscar Albayalde said in a statement.

Albayalde urged the public to stop sharing unverified documents that may cause due alarm.
